Emil Aldren Johnson, Furniture upholstery for schools (1919)
“ Burlap is the best material to use over webbing and over springs. It will not rip and tear as readily as most textiles and it is therefore a preferred material. Burlap comes in three weights: light (8 oz.) , medium (10 oz.) , and heavy (12 oz.) . The medium weight is best adapted for our work. This may be purchased for 9 cents a yard. It is 40 inches wide. Used burlap may ordinarily be purchased at local dry-goods stores for about 5 cents per pound. Even considering waste, this is much cheaper and quite as good as new burlap for the work intended.
